Tools/raw materials: Dell XPS 13-9350-3708, win 10, drive C.

1, open my computer, right-click on drive C and select Properties → Clean Disk, so that some surface garbage and fragmentary files in drive C can be cleaned up first.

2. After typing "C: \ Windows \ Software Distribution" in drive C, delete all files in the download folder. The files in this folder are patch files updated by the computer system and need to be cleaned manually.

3. After entering the "C: \ users \ computer user name \ \AppData\Local" path of drive C, all files in the Temp folder can be deleted. The Temp folder is full of cache files, which can be cleaned regularly.

4. Finally, download a slimming software for disk C in Baidu Software Center, and move all the software programs installed on disk C to other disks, so that disk C will save a lot of space.

The reason why disk c is full of red.

1, remaining files and applications. When installing and uninstalling applications, sometimes some useless files or registry keys are left behind. These files will occupy the space of drive C, and will increase gradually over time. If these residual files are not cleaned up in time, it will lead to a waste of space on disk C. Some applications may still retain some background processes or services after uninstallation, which will also take up space on disk C.

2. Temporary files and logs. A large number of temporary files and logs will be generated during the operation of computer systems. These files are usually stored on disk C, because disk C is a system disk, which usually has a high reading and writing speed. If these temporary files and logs are not cleaned up in time, it will also lead to the waste of disk C space.

3. Video and audio files. Video and audio files usually take up a lot of storage space.
